Water and energy: key elements of the future. The Inversions-Technik GmbH offers an advanced technique for treating waste water and treatment of liquid media. The machines are used as agitators, circulators and surface aerators. This agitation and aeration technique is based on a three-dimensional and pulse-like movement and on a special shaping of the stirring body, the OLOID. The result: the most economical use of energy and the best possible solutions in the process and environmental engineering.
